The present paper reviews recent research on perceptual latency priming (PLP). PLP is the relative latency advantage-earlier perception-of a visual stimulus that is preceded by another, masked stimulus at its location. The first stimulus attracts attention which accelerates perception of the second stimulus. This facilitation arises even if the first stimulus is visually backward-masked by the second one. The paper summarises research on temporal and spatial properties of PLP and the question whether intentions mediate shifts of attention to external events. Possible sources of PLP besides visuo-spatial attention are discussed. Finally, I give a review of feedforward and reentrant models of PLP and compare them to the empirical evidence.
本文回顾了近期关于知觉潜伏期启动（PLP）的研究。PLP是指在某一位置上，一个视觉刺激之前出现另一个被掩蔽的刺激时，该视觉刺激所具有的相对潜伏期优势——即更早被感知。第一个刺激吸引注意力，从而加速对第二个刺激的感知。即使第一个刺激在视觉上被第二个刺激逆向掩蔽，这种促进作用依然会出现。本文总结了关于PLP的时间和空间特性的研究，以及意图是否介导对外部事件的注意力转移这一问题。文中还讨论了除视觉空间注意力之外，PLP可能的来源。最后，我对PLP的前馈模型和折返模型进行了综述，并将它们与实证证据进行了比较。
